SPECIFICATION forming part of Letters Patent No. 707,188,dated August19, 1902.

Appnotiim'ied April' 251 19o2.

T0 all whom t may cor/toorn:

Be it known that`1, SAMUEL J WALKER, a`` citizen of the United States,residing atfLeesvi11e,in the parish of Vernon and State of Louisiana,have invented a new and useful Force-Draft Attachment for Stoves, ofwhich the following is a specification.

This invention relates to stoves and furnaces, more particularly tocook-stoves; and 1o artificial air-currents are adapted to be projectedinto the draft-chamber to increase the draft, as hereinafter shown anddescribed, and specifically pointed out in' the claims.

The device may be attached to any form of stove or furnace, but, asabove stated, is more particularly applicable to cook-stoves, and forthe purpose of illustration it is shown in the drawings applied tothefront of an ordinary cook-stove.

Figure l represents a front elevation of a portion of a stove-front withthe'device at-" tached thereto. Fig. 2 is a horizontal section'of thesame.

The device will generally be applied to the front of the stove 10,preferably in connection With the draft-slides l1, and consists in acylinder or tube 12, attached,as bylugs 12, across the front of thestove and having small branch pipes 13 leading laterally therefrom andending opposite the draft-apertures, as shown. Within the cylinder ismovably disposed a piston 14, having a stem 15 leading outward throughone end and provided with an operating-handle 16. By this simplearrangement it will be readily understood when the piston is moved backand forth in the cylinder the air will be alternately drawn into thecylinder throughthe branches 13 4o and projected forcibly therefromintoqthe draft-chamber through the 'draft-apertures;

The device is verysimple and easily apit consists in an attachmentwhereby strong sentir.104,685.1(110 man.)

plied to any stove or furnace Without changing 'the' latteryor'alterirgany of itsparts'and will be found very convenient Whereforced` or induced currents are required.

The cylinder 12 may be of any desired size, and any desired number ofthe branch pipes 13 maybe employed, but generally they will correspondto the number of the draft-apertures, as shown.

What I claim is- 1. An attachment to a stove comprising a cylinderhaving one or more'outlets in alinement with the draft-apertures, apiston movably disposed within said cylinder,and means 'whereby air isadmitted to the cylinder during the movement of the piston in onedirection and discharged from said outlets when said piston is moved inthe opposite direction, substantially as described.

. 2:An attachment; tolastovencomprising a cylinder-,having one or moreoutlets communicatingwith the" draftchamber, a piston movably disposedWithin said cylinder, and L1neanslvvherebyair is admitted to thecylinder during the movement of the piston in one direction anddischarged from said outlets when said piston is moved in the oppositedirection, substantially as described.l

3. The combination With a lstove having draft-apertures, of a cylinderwith lateral outlets in alinement with said apertures, va piston movablydisposed Within said cylinder, and means for operating said piston,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses. A

SAMUEL J. WALKER'.
